Referring to fig. 2, fig. 2 is a schematic flow chart of a vehicle driving monitoring method according to an embodiment of the present invention, and as shown in fig. 2, the vehicle driving monitoring method includes the following steps:
step 201, obtaining an environment image in a visual area of the camera terminal.
The camera terminal may be an image capturing device with a shooting function, such as a mobile phone, a camera, a tablet, and the like. The camera terminal is arranged on the position adjusting support, the position adjusting support is provided with an adjustable device, the rotating angle (direction) of the support is adjusted to adjust the shooting angle (direction) of the camera terminal, the adjustable device can be a holder, and the adjustable device is in signal connection with the camera terminal, for example, the adjustable device can be electrically connected with the camera terminal and can also be in wired or wireless network connection with the camera terminal. The direction adjusting support is arranged in the vehicle, can be arranged on the inner side of the wind shielding upper end of the vehicle, can be arranged on the back of a rearview mirror, and can also be arranged below the rearview mirror. In the present embodiment, it is preferable that the orientation adjusting bracket is disposed inside the upper end of the windshield glass such that the camera of the camera terminal faces the vehicle traveling direction. The vehicle may be referred to as an automobile.
Optionally, two groups of camera terminals and a position adjusting support can be arranged in the vehicle, and one group of camera terminals and a position adjusting support are arranged in the vehicle head direction and used for monitoring the driving condition of the vehicle head direction. The other group is arranged in the direction of the tail of the vehicle and used for monitoring the driving condition in the direction of the tail of the vehicle. Therefore, the driving videos of the direction of the vehicle head and the direction of the vehicle tail can be collected, the monitoring range of the vehicle is enlarged, and the vehicle monitoring efficiency is further improved.
The visible area of the camera terminal can be a visible area of a camera of the camera terminal, for example, an area of a windshield of a vehicle facing the head of the vehicle, which can be shot by the camera of the camera terminal. The position of the visible area of the camera terminal can be changed along with the shooting direction of the camera terminal, for example, the camera terminal shoots towards the direction of the vehicle head, and the visible area of the camera terminal is the area of the direction of the vehicle head, which can be shot by the camera of the camera terminal. If the camera terminal shoots towards the left side of the head of the vehicle or towards the left front side of the head of the vehicle, the visible area of the camera terminal is the left side of the head of the vehicle or towards the left front side of the head of the vehicle, and the area can be shot by the camera of the camera terminal.
The environment image may be an image captured by the camera terminal in a visible area of the camera terminal.
Specifically, in step 201, the image is captured by the camera terminal in the visible area of the camera terminal to obtain the environment image.
In one embodiment, before step 201, if the shooting function of the camera terminal is turned off, the camera terminal needs to be turned on.
In one embodiment, before step 201, the camera terminal needs to determine whether the camera terminal is mounted on the orientation adjustment bracket, and when the camera terminal is mounted on the orientation adjustment bracket, the camera terminal establishes a connection with the orientation adjustment bracket. This enables communication between the orientation adjustment and the camera terminal. And only set up on the position adjustment support at camera terminal can adjust the support through this position of camera terminal control to adjust camera terminal's shooting direction, can go and carry out effective control to the vehicle.
The method for judging whether the camera terminal is mounted on the orientation adjusting bracket by the camera terminal may be to judge by detecting a signal of a preset interface. For example, when the signal of the preset interface is detected to be high level, it indicates that the camera terminal is arranged on the hair orientation adjusting bracket.
In an embodiment, before step 201, the camera terminal needs to detect whether an automobile data recorder is installed on the vehicle, and if the automobile data recorder is installed, it detects whether the automobile data recorder is turned on, and if the automobile data recorder is not turned on, it controls the automobile data recorder to be turned on, so that the automobile data recorder and the camera terminal can jointly monitor the vehicle. The vehicle event data recorder is in communication connection with the camera terminal, for example, the vehicle event data recorder can be in electrical connection, and can also be in wired or wireless network connection.
And 202, carrying out image recognition on the environment image, and obtaining vehicle driving information of the vehicle based on the recognition result.
The vehicle driving information comprises vehicle driving speed information, position information between objects around the vehicle and the vehicle, and vehicle driving road condition information. The vehicle driving information may also include driving time period information, such as night driving, day driving, and the like. And the system can also contain driving weather information, such as driving in rainy days, driving in foggy days, driving in snowy days and the like.
Specifically, the collected environment image is subjected to image processing by a moving target detection method such as an optical flow field method, an inter-frame difference method, a background subtraction method and the like, so that the running speed of the camera terminal is obtained.
Whether an object exists in the environment image or not can be identified through an image identification technology or an image identification engine, if the object exists, the position relation between the object and the vehicle is identified, and for example, the left side, the left front, the right side, the right front and the like of the object in the environment image in the vehicle are identified. The object may be a vehicle, a pedestrian, an obstacle, etc. The object may be a moving object relative to the vehicle or a stationary object relative to the vehicle. The environment image may have one object or a plurality of objects, or may have no object.
The environment image can be identified through an image identification technology or an image identification engine, and then the vehicle driving road condition information can be identified, for example, the road conditions such as a flat road surface, a muddy road surface, a hollow road surface, a mountain road, a cement road, a tunnel and the like. And the road condition can be unobstructed high-speed road condition, congested complex road condition and the like.
And step 203, controlling the direction adjusting bracket to rotate according to the vehicle driving information so as to adjust the shooting direction of the camera terminal.
The shooting direction may be a shooting angle, a shooting orientation, or the like.
Specifically, when the environment image is identified to obtain different vehicle driving information, the corresponding control instruction generated by the vehicle driving information can be sent to the position adjusting support to control the position adjusting support to rotate, so that the camera terminal arranged on the position adjusting support is driven to rotate correspondingly, the shooting direction of the camera terminal is adjusted, the camera terminal is adapted to the corresponding vehicle information, and the vehicle can be effectively monitored.
For example, when the vehicle driving information includes driving at night, the direction adjusting bracket is controlled to rotate so as to adjust the driving direction of the camera terminal towards the vehicle for shooting. Therefore, the vehicle and the running environment thereof can be monitored by means of the light of the vehicle at night.
It should be noted that, the controlling the position adjusting bracket to rotate may specifically be controlling an adjustable device, such as a pan-tilt, on the position adjusting bracket to rotate.
And step 204, transmitting the image shot by the camera terminal to the user terminal.
The user terminal may be a mobile device used by a user, such as a mobile phone, a tablet computer, a notebook computer, a desktop computer, and the like. The user terminal may be one or more. The camera terminal and the user terminal can communicate through a network.
Specifically, images shot by the camera terminal are sent to the mobile device for storage, so that a user can view historical image data of the vehicle conveniently; when the user needs to view the historical images, the user can view the images saved on the mobile device. The user can also check the driving image of the vehicle in real time through the mobile device, so that the user can conveniently monitor the vehicle.
In another embodiment, the image captured by the camera terminal can also be sent to a server or a network disk for storing the image captured by the camera terminal. Or synchronized to the user terminal through the server or the network disk for storage, processing or display. When the history image is viewed as needed, the image data can be extracted by the user terminal accessing the server or the network disk.
In an embodiment, the camera terminal may store the captured image in its own memory, such as a system memory of the camera terminal and an SD card (secure digital card), so that the user may also obtain the history image by querying the memory on the camera terminal for reference.
It should be noted that storing images captured by the camera terminal to different user terminals can avoid the problem that the data of the camera terminal is lost and cannot be called.
In an embodiment, when the stored image data is more and more, the stored image data may be stored in a partitioned manner according to a certain partition condition, where the partition condition may be a preset time threshold, and the preset time threshold may be 3 months, 6 months, 1 year, and the like, and the preset time threshold may be set as needed. And when the storage time of the stored image data exceeds a preset time threshold, refrigerating the image data exceeding the preset time threshold, and storing the image data into a specific storage partition. For example, the image data exceeding the preset time threshold may be stored in a memory such as a magnetic disk or a hard disk. This saves storage space on the user terminal, and new image data can be stored later, also to avoid loss of history data.
The stored image data is convenient for the user to process, display, view, and the like the image. The method can also be used for reference of third-party users, for example, when a traffic accident happens to the vehicle, law enforcement agencies or insurance companies can view historical image records of the vehicle, so that the reason for the accident occurrence, the claim settlement and the like can be conveniently judged for reference. When the vehicle is stolen, the position of the vehicle can be judged by uploading the image data to a user end, a server or a network disk.
In the embodiment of the invention, the environment image in the visible area of the camera terminal is obtained; carrying out image recognition on the environment image, and obtaining vehicle driving information of the vehicle based on a recognition result; controlling the direction adjusting bracket to rotate according to the vehicle driving information so as to adjust the shooting direction of the camera terminal; sending an image shot by the camera terminal to the user terminal; the vehicle driving information comprises vehicle driving speed information, object information around the vehicle and vehicle driving road condition information. Therefore, the vehicle driving information can be obtained according to the identification result analysis of the environment image, the shooting direction of the camera terminal can be adjusted through the position adjusting support according to the difference of the vehicle driving information, the camera terminal can shoot the environment image in different directions, and the effective monitoring of vehicle driving can be realized. The invention can automatically adjust the shooting direction of the camera terminal, solves the problem of poor monitoring effect of vehicle running caused by limited shooting angle of the automobile data recorder in the prior art, and further improves the monitoring effect of vehicle running.
Referring to fig. 3, fig. 3 is a flowchart of a method provided in step 203 of fig. 2, where step 203 includes, as shown in fig. 3:
The preset distance threshold may be a preset distance threshold between the object and the vehicle. The distance threshold may be set to 50 cm, 1 meter, 5 meters, 10 meters, 50 meters, etc., and may be set according to actual needs. The preset distance threshold is used to determine whether there is a risk boundary between the object and the vehicle, and the preset distance threshold may also be referred to as a safety distance. For example, the preset distance threshold is set to 5 meters, and when a vehicle appears right ahead of the vehicle and the distance between the vehicle and the vehicle is less than 5 meters, it can be determined that two vehicles may have the risk of rear-end collision or collision.
Specifically, when an object is detected to be present in the environment image, the distance between the object and the vehicle is calculated, the distance between the object and the vehicle is determined according to a preset distance threshold, and if the distance between the object and the vehicle is within a preset distance range, it is determined that the distance between the object and the vehicle reaches the preset distance threshold. When the distance between the object and the vehicle is greater than the preset distance threshold, the fact that the distance between the object and the vehicle does not reach the preset distance threshold is indicated.
When calculating the distance between the object and the vehicle, the camera terminal needs to be corrected, and the distance between the object and the camera terminal minus the distance from the camera terminal to the edge of the vehicle body is equal to the actual distance between the object and the vehicle.
And 302, if the preset distance threshold is reached, controlling the direction adjusting support to rotate so as to adjust the camera terminal to shoot towards the object.
Specifically, when the distance between the object and the vehicle meets a preset distance threshold, it is described that a hidden risk exists between the object and the vehicle, the camera terminal is required to control the azimuth adjusting support to rotate at the moment, the camera terminal shoots towards the object, and the dynamic situation between the object and the vehicle is monitored and recorded constantly. For example, if a vehicle appears on the left side of the vehicle and the distance between the vehicle and the vehicle is smaller than a preset distance threshold, a risk of rear-end collision may exist between the two vehicles, and at this time, the camera terminal needs to control the azimuth adjusting bracket to rotate, and make the camera terminal shoot towards the right front of the vehicle all the time, so as to monitor the dynamic situation between the two vehicles at any time. If the two vehicles collide and scratch, the images can be shot by the camera terminal, so that reference can be made to subsequent handling accidents.
In one embodiment, the camera terminal can send the shot images to the vehicle-mounted terminal in real time and display the images, so that driving of a driver is facilitated to be assisted. For example, when two vehicles converge, a visual dead angle always exists on the left or right of the driver, and then the driver can assist driving through a real-time image which is sent to the vehicle-mounted terminal by the camera terminal and displayed. In the embodiment of the invention, when other objects around the vehicle are detected according to image recognition, the detected objects can be shot by combining with the preset distance threshold, and further the dynamic situation between the objects and the vehicle can be monitored. When a plurality of objects are detected simultaneously, the objects are not required to be monitored simultaneously, and the objects with the distances between the objects and the vehicle meeting the preset distance threshold value are selected for monitoring, so that the monitoring efficiency of vehicle running is further improved.
Referring to fig. 4, fig. 4 is a flowchart of another method provided in the embodiment of step 203 in fig. 2, as shown in fig. 4, before step 301, step 203 further includes:
And step 402, determining a preset distance threshold corresponding to the position information based on the position information.
Specifically, when an object is detected in each of a plurality of directions of the environment image, that is, a plurality of objects are detected in the vicinity of the vehicle in the actual environment, it is necessary to determine the distances from the objects in the different directions to the vehicle, respectively, and to acquire the distance thresholds in the plurality of directions, which are set in advance, respectively.
It should be noted that, distance thresholds between the object and the vehicle may be preset in different directions of the vehicle, for example, a preset distance threshold between the object right in front of the vehicle and the vehicle is preset to be 10 meters; presetting a preset distance threshold value between an object in the left front of the vehicle and the vehicle to be 5 m; presetting a preset distance threshold value between an object on the left side of the vehicle and the vehicle to be 50 cm; presetting a preset distance threshold value between an object in the right front of the vehicle and the vehicle to be 5 m; the preset distance threshold value between the object on the right side of the vehicle and the vehicle is preset to be 50 centimeters.
In the embodiment of the invention, different preset distance thresholds are set in different directions of the vehicle, so that the camera terminal can conveniently monitor objects at different positions of the vehicle. Further improve the monitoring efficiency that the vehicle travel.
Referring to fig. 5, fig. 5 is a flowchart of another vehicle driving monitoring method according to an embodiment of the present invention, and as shown in fig. 5, the vehicle driving monitoring method includes the following steps:
and step 501, obtaining an environment image in a visual area of the camera terminal.
And 502, carrying out image recognition on the environment image, and obtaining vehicle driving information of the vehicle based on a recognition result.
And 503, when the vehicle running information is that the current speed of the vehicle is detected to exceed a preset speed threshold value, controlling the direction adjusting support to rotate so as to adjust the camera terminal to shoot towards the vehicle running direction.
Specifically, the camera terminal can detect the current running speed of the vehicle by identifying the environment image, compare the current running speed of the vehicle with a preset speed threshold value, and when the current running speed exceeds the preset speed threshold value, the camera terminal needs to control the azimuth adjusting support to rotate so as to adjust the camera terminal to shoot towards the running direction of the vehicle. Thus, the running state of the vehicle can be effectively monitored.
In another embodiment, the step of controlling the orientation adjustment bracket to rotate according to the driving information of the vehicle to adjust the shooting direction of the camera terminal comprises:
when the vehicle driving information is that the pedestrian volume in the vehicle driving direction is large, the direction adjusting support is controlled to rotate so as to adjust the camera terminal to shoot towards the vehicle driving direction. It should be noted that, if the traffic in the current driving direction is large, it can be determined that the range that can be photographed is larger when the range of the angle of view of the camera terminal photographing towards the front of the vehicle is the largest, and the monitoring effect of the vehicle driving is further improved.
And step 504, sending the image shot by the camera terminal to the user terminal.
In the embodiment of the invention, the camera terminal can control the azimuth adjusting bracket to rotate through the current running speed of the vehicle so as to adjust the camera terminal to shoot towards the running direction of the vehicle. Further improve the monitoring efficiency that the vehicle travel.
